arproxy-plugin-stdout

とりあえずサンプルプラグインを作ってみた。

https://github.com/winebarrel/arproxy-plugin-stdout

実装は以下の通り。

https://github.com/winebarrel/arproxy-plugin-stdout/blob/master/lib/arproxy/plugin/stdout.rb

module Arproxy::Plugin
  class Stdout < Arproxy::Base
    Arproxy::Plugin.register(:stdout, self)

    def execute(sql, name=nil)
      puts sql
      super(sql, name)
    end
  end
end

使い方

RailsのGemfileにarproxyとプラグインを追加。

gem 'arproxy', '~> 0.2.0'
gem 'arproxy-plugin-stdout', github: 'winebarrel/arproxy-plugin-stdout'

config/initializers/arproxy.rbでプラグインをロード。

Arproxy.configure do |config|
  config.adapter = "mysql2"
  config.plugin :stdout
end
Arproxy.enable!

Railsを起動してアクセスすると標準出力にSQLが出力される。
